2002 Isuzu Trooper Question: check engine

what is code p-1870 no dtc? -
Answer 1
this is a transmission fault; here's some info: Range switch malfunction could set a DTC P1870. A mechanical failure of the shift solenoids, TCC solenoid, or TCC PWM solenoid could set a DTC P1870. Internal transmission failures may set a DTC P1870. An intermittent or incorrect engine speed signal may set a DTC P1870. there are several tests a shop can run to identify the cause. definitely not a DIY repair. -
